Ah, I didn't pay enough attention to your original post and as a result I focussed only on the flasher unit.
I was actually assuming that you were fitting full led replacement indicators rather than just bulbs.
My earlier response still stands but I would also add that the serious issue that I have found when replacing any incandescent bulbs with led "bulb" units (be that in indicators, rear lights or in particular headlights) is that in almost all cases the position and direction of the led light source is not compatible with the reflector in the original unit. That is to say, no matter how good the condition of the original reflector, it will probably not work at all well with an led "bulb" unit.
The only successful led conversion of original units that I have achieved was using a circuit-board array of (perhaps 30 or more) red led's which replaced the reflector entirely in my tail light. This gave a light source across the whole area of the light unit, rather than the very limited source area given by an led "bulb", and it works very well indeed, producing an output which is only slightly brighter than the original but which has a much deeper colour which extends across the full area of the lens rather than being brighter in the centre. The end result is that its much more visible without being annoyingly bright. Dunno where it came from ... it was given to me by Capo.
For this reason I would avoid "upgrading" to led "bulbs" in original equipment but would instead either leave well enough alone or replace the entire units with ones designed for led's. This was why I fitted the Panigale led indicators to my bike.
Ben ... that's interesting info .... and now that you mention it, I think I recall.
I might look into that.
It would be worth getting a batch done I reckon.
Do you remember any details of the material used ?
